Anyone knows if I can go on this spoke count or I have to go up to 24/28 which I'm not fancy of.

I'm 170lb (75KG) and I'm not planning to go up on weight, I'm not racing, just training and like mainly to look for climbs. I'm not an aggressive rider as I said I'm not racing. My main question for you out there if this wheelset I have described is strong enough.

On the 340s I would go 24/28H even if you don't race......you are probably looking at 50-60 extra grams.You could switch to Sapin CX-Ray and lower the weight...or if your budget allows maybe a Mig 45 up front.

I've got the mk2 340s rim built 28h onto old record hub. 24h on tune mig up front on a 340s mk.1. Have regretted going 24h front, you can definitely go with 20h front.

With about 4k kms on that rear wheel, I think its about right for my riding / weight - which is generally moderate to good condition roads with very occasional roads that see farm traffic which have large pot holes & uneven surfaces. Generally mixed use on hills & rolling terrain. I've needed to true it once or twice & that's just for the sake of having it running at >.5mm side to side in true - its held up pretty well.

If you want the build to last & not have to pay it attention I'd go with 28h. If you don't mind dropping it into a stand every 1-2k kms then you can go with 24h. You may have better roads & finesse than me, but that has been my experience with the build. YMMV etc...

Do get them built up as evenly as possible & with a lot of care - they are a lighter rim, so can't be quickly & roughly built up imo if the are going to stay round & true for long term.

FWIW I've also used a 32h set of mk.1 stans for parts of this past season as a training set - they've held up pretty well, have needed a bit of attention about 2k kms in, but have settled down for about another 3k kms beyond that without needing any other adjustments or truing.

I think that the 20/24 hole count is one that you could get away with. I don't think that it would be ideal though. The 340 is a relatively soft hoop and I've always felt that it needs to be overbuilt a bit. With that said, go with a 20/28 or 24/28 hole count. I think that would be much more practical for your weight.

I think you will like the Tune hubs though. They seem to have consistent durability, even though they are quite light.

I had the exact wheelset but with sapim xray spokes laced up in 20/24. I weight 170 lbs and do not race. Road conditions in my area are quit good. I sold them because they were too flexy in both front and rear. I did not like the feel!

@WasFab- Well, realistically you could get away with either one. I do think that the 24/28 would be more ideal though. The 340 is by no means the stiffest hoop out there so you really can't overbuild it.

I have a set of Stans 340's (the newer version) laced with cxrays to Alchemy hubs, and on the advice of my builder went with 24 x1/ 28x3. I was also a bit concerned about the esthetics, but they actually look very nice, and I love the performance. The set weighs in at about 1275g (and I weigh in at about 59k)

@wasfab- We predominantly use the Cxray from Sapim. It seems to be resistant to gouging if your unfortunate enough to drop a cassette or whatnot. And they should build up to be pretty rigid. They aren't a truly bladed spoke (more ovalized) which keeps them aero even with a higher yaw angle.
